Refer to the exhibit, which contains a partial command output.

From the BGP neighbor status output, the key issue is that BGP is stuck in the "Idle" state, meaning the FortiGate is unable to establish a BGP session with its peer 100.65.4.1 (Remote AS 65300).

The output also shows:

● "Not directly connected EBGP" → This means the BGP peer is not on the same subnet, requiring multihop BGP.

● "Update source is Loopback" → Since a loopback interface is used, FortiGate must be configured to allow BGP neighbors over multiple hops.

To resolve this issue, the administrator must enable ebgp-enforce-multihop, which allows BGP sessions to be established even when the neighbors are not directly connected.
